This if the fourth campaign manager that Gallego has named since he became a candidate for the congressional seat, which is important to both Democrat and Republican plans to control the House of Representatives.

The Canseco campaign said the changes show “turmoil and an inability to run a campaign” on the part of Gallego.

“This further signals that this turmoil has not ceased and it makes you wonder, if you can’t even run a campaign, how can you represent a district as large and complex as the 23rd (Congressional) District of Texas,” said Scott Yeldell with the Canseco campaign.

The Gallego campaign first hired an Austin consultant before changing to out-of-state consultants.

The candidate again overhauled his campaign when he failed to win the Democratic primary outright.

Gallego hired Rotkoff to run the Democratic primary runoff campaign. Gallego received 55 percent of the vote and defeated former Rep. Ciro Rodriguez, D-San Antonio, to set up his challenge to Canseco.

Gallego has attacked Canseco as a right-wing extremist. Gallego said his new campaign staff would help contrast his record with that of Canseco’s to inform voters of their choice in the election.
